PURPOSE: A wave end mil is provided to achieve high speed rotation and high transfer by reducing cutting resistance with a work piece made from non-ferrous metal. CONSTITUTION: A wave end mil comprises a shank(110), a spiral groove(120), an outer blade unit(130), and a bottom blade unit(140). The shank is combined with a milling machine. The spiral groove is cut like a wave type around its circumference. The peripheral blade park is formed like a wave shape along a spiral groove. The bottom blade part is extended from the peripheral blade part, and formed in the lower end of the shank. The shank transmits torque from a milling machine onto a work piece. The shank is cylindrical type and made from hard-metal cemented carbide. The spiral groove keeps or expels cutting chip occurred in the course of cutting process. The spiral groove has a wave shape at constant cycle.
